Level 892 is the second level in Crumbly Coast and the 23rd moves level.
To pass this level, you must score at least 45,000 points in 40 moves.
When you complete the level, Sugar Crush is activated and will score you additional points.

You will get at least 9,680 points (440 for the chocolate, 6,840 for the UFOs and 2,400 for making matches of three for all 40 moves), so you need to get approximately 35,000 points, that is not hard, if you create special candies.
